Geometry Topology Working Seminar
Friday, November 3, 2017 - 1:55pm
1.5 hours (actually 80 minutes)
In this series of talks I will introduce branched coverings of manifolds and sketch proofs of most the known results in low dimensions (such as every 3 manifold is a 3-fold branched cover over a knot in the 3-sphere and the existence of universal knots). This week we sstart discussing branched covers of 3-manifolds.
